A OIL SEPARA'I'OR.

iaoaese;

Application filed May 11,

of N ew .York city, borou hl of Brooklyn, in y thefcounty ofi-Kings and State of New York` have" invented a newfa'nd' Improved 7 clear, and eXactdescription.

This inventionrela'tes to.oil and air separators and has for an object to provideV an improvedconstruction especially .adapted for use in connection with' compressors, the arrangement being such that the sealing oil in the compressor is relieved from its air without interrupting the compressingv or without necessitating the use of a large amount of oil.

Another object of the invention is to provide'a separator forv separating oil and air,

wherein a plurality of bailiing and expansion chambers arel arranged to successively cause a deposit or precipitation of the oil while the air moves to a discharge point.

v 1.5iv still further object of the invention, more specifically, is the provision, in an oil and air separator, of a baille and a straining member arranged in such a manner .as to permit the passage of air withoutappreciable back pressure while causing a thorough separation of the air and oil.

ln the accompanying drawing:

Figure 1 is a side view of a compressor with an oil and air separator shown in connection' therewith, the same being `in section for better illustrating the construction thereof.

Figure 2 is a fragmentary sectional view through partof a slightly modified form of se arator to that shown in Figure 1.

eferringv to the accompanying drawings by numeral, 1 indicates an air compressor of any desired kind which receives air through the inlet member 2 anddischarges the same through the pipe 3 into the separator 4. Oil

is led from pipe 5 or from any other source to the air opening 2 so as to provide a sealin r liquid in the compressor 1 at all times. Air discharge pipes 6 and 7 are vconnected with the separator 4, said pipes having controlling valves of any -desired kind so that air may be taken from either pipe or both pipes. Separator 4 is provided with a casing 8, divided into chambers 9 and 10 by division plate 11,. This plate may be held in `-place in any suitable manner and is prospecication of Letters Patent.

vided with a number of apertures 12 tapering or flaring from the lower side of the plate to the upper side. This plate is also provided with a flange 13` to which a foraminous member 14 is secured byv bolts or in any other suitable manner. This member 14 is also bolted or otherwise secured to a dependent flan e 15 used integral with the cap member 16 of casing 8. A defiector 17 is also connected .with the plate 11 by a bolt 18 or in some other desirable manner, said deflector having af plurality of webs 19, whereby grooves 2 0y are provided. Theauxiliary pipe 3 .extends upwardly 4into the, cone-shaped defiector 17 so that the air and oil may be vlrtentecl Jan. 31, 1922*.

9, and' from thence around the lower edge of the deflector 17 to the plate 11. i Most of the oil is removed fromthe air by the deliector 17 but as the air passes through the apertures 1-2, most, if not all, 'of the remain. ing 'oil is removed, especially when operating at comparatively low pressure. Whe'n this 'is the case, air is usually-drawn off or permitted to4 pass out through pipe 7. When operating at a higher pressure, the air is, preferably caused to pass through the foraminous member 14 and out pipe 6. This member is arranged vertically, whereby the air must change 'direction in order to pass therein. This changing of direction is difficult for the oil and, consequently, the oil, will be deposited on the exterior surface by member'14 and willl run down through the apertures 12 into chamber 9, where` it is collected and discharged through the p1pe 5. In this way, ample oil may be provided for sealing the blades of the compressor 1 and at the same time, the air free of oil discharged out through the pipe 6 or 7. Under some circumstances, additional cleaning action may be desirable. When such is the case, a supply of fibrous matter 21 1s arranged on the upper surface of the plate 11, as shown in Figure 2. This fibrous matter may be as bestos, cotton or other material.

What I claim is:

1. An oil and air separator of the characvnous plate dividing the casing centrally into an inlet compartment andan outlet compartment, a drain pipe-connected to the bottom part of the inlet compartment, an' inlet pipe' extending through the center of the bottom of'said inlet compartment and through the inlet compartment to near said .foraminous plate7 an outlet pipe connected to said casing at the end opposite to said inlet pipe, an auxiliary outlet pi e connected Wit-h 'Said casing adjacent sai foraminous plate and opening into said outlet compartment, means carried by said foraminous plate for deiecting the matter entering said inlet chamber and means arranged in the outlet chamber for causing the air to changedirection be fore it passes into said outlet pipe.

2. An oil separator of the character described comprising a casing, a foraminous plate dividing the casing into inlet and outlet compartments, a tube extending vertically into the inlet compartment and to nearA the foraminous plate, an inverted coneshaped member secured to said foraininonsplate and overlapping said tube-,12al'italolafZt member arranged in said outlet eoniintrt-A nrent, said tubular member being foraminoue, and means for directing air from the i interior of said tubularmember.`

3. An oil separatol` of the character de- -scribed comprising a casing, a" forammous fnnvvann a. naaien.
